Vortex Fan Shroud

thingiverse

Here is the rewritten text: I converted a standard 40mm x 40mm fan into a powerful Blow Radial type output. To cool the extruded filament on my 3D printer, I attached this conversion to a 40x40 fan and it works incredibly well in directing airflow. I didn't need to disassemble the fan or remove its blades, making this modification much easier than others I've found online.
